Chapter 6. Upgrading and replacing devices

Replacing memory ------------------------------------------------------------------------------------------------------

You can increase the amount of memory in your computer by installing a double data rate (DDR 2) small outline dual inline memory module (SO-DIMM)-available as an option-in the memory slot of your computer. SO-DIMMs are available in various capacities.

Note: Use only the memory types supported by your computer. If you incorrectly install the optional memory or install an unsupported memory type, a warning beep will sound when you try to start the computer.

To install an SO-DIMM, do the following:

1Touch a metal table or a grounded metal object to reduce any static electricity in your body, which could damage the SO-DIMM. Do not touch the contact edge of the SO-DIMM.

2Turn off the computer. Disconnect the AC adapter and all cables from the computer.

3Close the computer display, and turn the computer over.

4Remove the battery pack.

5Remove the Memory/Wireless module/CPU (central processing unit) compartment cover.
